You know him best from “Drumline” and “The Replacements” but writer/producer/actor/comedian Orlando Jones has been working behind the scenes for years. He started out at 19 writing for “A Different World” and “Martin” and he also worked on “Roc” and “MadTV.” You could say he knows a thing or two about multiple revenue streams as he’s also a standup comic. Yup, he’s at the Arlington Improv near Dallas this weekend.
